Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628966, here are decompositions:

29 + 8628937 = 8628966
43 + 8628923 = 8628966
53 + 8628913 = 8628966
67 + 8628899 = 8628966
83 + 8628883 = 8628966
107 + 8628859 = 8628966
109 + 8628857 = 8628966
167 + 8628799 = 8628966

Showing the first eight; more decompositions exist.
